Abstract
The invention discloses a medical appliance, in particular a safe intravenous infusion needle. The safe intravenous infusion needle comprises a connecting pipe; the upper end of the connecting pipe is connected with a needle bed; the lower end of the connecting pipe is connected with a puncture needle head and a needle wing; an initial protective pipe is sleeved outside the puncture needle head; and the safe intravenous infusion needle is characterized in that: an anti-stab sleeve is additionally arranged outside the puncture needle head; one side of the anti-stab sleeve is provided with an elongated slot; and the needle wing is positioned inside the elongated slot. The safe intravenous infusion needle has no difference in the puncture use from a common intravenous infusion needle; however, after use, the needle head can be fully wrapped by the anti-stab sleeve; therefore, the safe intravenous infusion needle effectively prevents the occurrence of stab, reduces the probability of spreading disease through blood, is very convenient to use, can achieve good effect of protecting medical personnel and others, has simple manufacturing and low cost, and cannot increase economic burden for patients.
Description
(1) technical field
The present invention relates to a kind of medical apparatus, particularly a kind of safe intravenous infusion needle.
(2) background technology
In present medical domain; more and more through the disease that blood is propagated; the annual according to statistics whole world has nearly 1,000,000 syringe needles accident of stabbing to take place; being in the great majority wherein because of the venous transfusion needlestick injury; so the medical worker to patient carry out after the venipuncture used syringe needle be a very big potential safety hazard; because the syringe needle after the venipuncture now all is to expose outside; after the medical worker need pack up whole transfusion device and take back therapeutic room, piercing needle is taken in sharp disposable container after puncture is finished to venous patient; syringe needle is pricked medical worker or other people through regular meeting in this whole process; might infect a lot of diseases, so prevent that exhausted needle sting medical personnel and other people member from being extremely important.
(3) summary of the invention
The present invention is in order to remedy the defective of prior art, and a kind of safe intravenous infusion needle of stabbing prevented is provided.
The present invention is achieved through the following technical solutions:
A kind of safe intravenous infusion needle; comprise connection tube; the connection tube upper end connects needle stand; the lower end of connection tube connects the piercing needle and the pin wing; piercing needle is with initial protecting tube outward; it is characterized in that: set up an anti-sleeve pipe of stabbing outside piercing needle, prevent that stabbing a telescopic side has elongated slot, the pin wing is positioned at elongated slot.
This safe intravenous infusion needle; the needle point of the piercing needle when being in guard mode is positioned at anti-cavity of stabbing casing shoe; elongated slot top and anti-distance of stabbing between the cannula tip equal the distance between pin wing top and the connection tube end; anti-when being in original state stabbed the 2mm place, end below, the draw point crown that casing shoe is positioned at piercing needle, and the anti-sleeve pipe of stabbing is provided with one and prevents that stabbing sleeve pipe pushes away handle.
The invention has the beneficial effects as follows: this safe intravenous infusion needle and common venoclysis needle indistinction in the use of puncture; but can wrap up syringe needle fully by anti-pricking wound sleeve pipe after using; thereby effectively prevent the generation of pricking wound; minimizing is by the probability of blood born diseases; very convenient when in use, can play a very good protection to medical worker and other people, and make simple; cost is low, can not increase financial burden to patient.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Structural representation when accompanying drawing 1 is protected for safe intravenous infusion needle of the present invention.
Accompanying drawing 2 is the preceding structural representation of safe intravenous infusion needle protection of the present invention.
Accompanying drawing 3 is stabbed telescopic structural representation for safe intravenous infusion needle of the present invention is anti-.
Among the figure, 1 piercing needle, the 2 pin wings, 3 prevent that stabbing sleeve pipe pushes away handle, the 4 anti-sleeve pipes of stabbing; 5 connection tubes, 6 elongated slots, 7 connection tube ends, 8 initial protecting tubes, 9 draw point crown ends; 10 prevent stabbing casing shoe, 11 elongated slot tops, and 12 prevent stabbing cannula tip, 13 cavitys, 14 pin wing tops.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This safe intravenous infusion needle; comprise connection tube 5; connection tube 5 upper ends connect needle stand 15; the lower end of connection tube 5 connects the piercing needle 1 and the pin wing 2; be with initial protecting tube 8 outside the piercing needle 1; it is characterized in that: outside piercing needle 1, set up an anti-sleeve pipe 4 of stabbing; an anti-side of stabbing sleeve pipe 4 has elongated slot 6; the pin wing 2 is positioned at elongated slot 6; the needle point of the piercing needle 1 when being in guard mode is positioned at anti-cavity 13 of stabbing sleeve pipe 4 bottoms; " and anti-distance of stabbing between the cannula tip 12 equals the distance between pin wing top 14 and the connection tube end 7; anti-when being in original state stabbed the 2mm place, draw point crown end 9 below that casing shoe 10 is positioned at piercing needle 1; make and anti-ly stab sleeve pipe 4 and can not hinder the medical worker that patient is punctured; the anti-sleeve pipe 4 of stabbing is provided with one and anti-ly stabs sleeve pipe and push away handle 3, is beneficial to promotion downwards and prevents stabbing sleeve pipe 4 on the elongated slot top.
This safe intravenous infusion needle; before the use; by needle stand 15 and tube for transfusion; fluidic switch; Murphy's burette; infusion bottles etc. connect; preparation just can be carried out venipuncture before carrying out transfusion; identical with common transfusion needle operation in the process of venipuncture; initial protecting tube 8 to be pulled out earlier and puncture can be begun; but after venipuncture is finished; only needing to prevent stabbing sleeve pipe 4 promotes downwards; make and prevent that stabbing cannula tip 12 is stuck between pin wing top 14 and the connection tube end 7; preventing to stab sleeve pipe 4 teetertotters; at this moment the needle point of piercing needle 1 just can be positioned at anti-cavity 13 of stabbing sleeve pipe 4 bottoms; piercing needle 1 is played a very good protection, prevented effectively that in the process of ambulatory infusion device piercing needle 1 from stabbing medical worker or other people.
